Open Questions On Nuclear Collective Motion

TL;DR

This paper reviews the current understanding of nuclear collective quadrupole modes, discussing both macroscopic and microscopic descriptions, and highlights challenges like non-adiabaticity and decoherence, while presenting a microscopic approach to yrast states.

Contribution

It provides a comprehensive review of nuclear collective motion and introduces a microscopic description of yrast states within the rotating mean field framework.

Findings

Limits due to non-adiabaticity and decoherence are identified.

Microscopic description of yrast states in vibrator-like nuclei is developed.

The review highlights open questions and challenges in nuclear collective motion.

Abstract

The status of the macroscopic and microscopic description of the collective quadrupole modes is reviewed, where limits due to non-adiabaticity and decoherence are exposed. The microscopic description of the yrast states in vibrator-like nuclei in the framework of the rotating mean field is presented.
